Looking at your old posts it looks like you have had very bad luck with your Supershapes.
Rennstall claims "all of our work is 100% guaranteed" so just take them back and go
over both skis with the tech. Get them to check flatness and bevels and explain it all
to you point by point. I am sure you two can figure out the problem.
I, like others here, love our Supershapes with a 1 and 3 tune.
As for alignment problems, visit a bootfitter. How about Brent Amsbury in Park City.
